HERMAN C. DREISVOGT, OF SANTA CLARA COUNTY, CALIFORNIA.

INHALING AND HEATING DEVICE.

To all whom it may concern:

Be it known that l, HERMAN C. DREIS- Your, a citizen of the UnitedStates, and resident of Santa Clara county, State of California, haveinvented a new and useful Improvement in inhaling and Heating Devicesfor Medicinal Purposes, described in the following specification.

The object of my invention is to provide a device by which water and airmay be heated, and the air saturated with the me dicinal properties offluid andother substances through or over which the air is passed; toprovide means adapted to convey heated air or air so medicated to themouth and nose of a person; to providemeans for conveying the heat ofthe water to any accessible partof a persons body, and to provide meansfor regulating the temperature and flow of the air, and heat andcirculation of the water, under the control of the person using thedevice.

The manner in which I accomplish my object is described in the followingspecification and illustrated in the accompanying drawings, in which:

Figure l is a perspective elevation. Fig. 2 is a transverse section.Fig. 3 is a longitudinal section on the line 33 Fig. 2. Fig. 4 is alongitudinal section on the line H Fig. 2, and Fig. 5 is a longitudinalsection of a water bag shown in Fig. 1.

In the drawings the reference letters and numerals indicate the sameparts in each of the figures.

The vertical parts A and bottom A are made preferably of thin sheetmetal of any desired or convenient size for a tank. This tank issupported on legs A of any desired length. At the top of the parts A aredouble folds A as shown in Figs. 2, 3 and 4-. Nithin these folds is awater compartment A adapted for the insertion of the vertical flange ofa lid. This tank is closed and made air-tight by a lid B having avertical flange B adapted to slide telescopically into the compartment Ain which it is surrounded with a body of water which prevents the escapeof air from the tank. Fixed to the folds A are projections C, G and G Onthe projections C a division plate D rests. On the projection C a screenD rests, and on projection C another screen 1) rests. In the spaceEbetween the screens D and D the leaves of the Eucalyptus, and any othersubstance required to impregnate the Specification of Letters Patent.

air is placed. Below and above these screens are air spaces and E In thewater space below the plate D are two coils of pipe. The coil adaptedfor hot water and is provided with a feed pipe F adapted in height tomaintain a-proper water pressure in the coil and its connections. On theopposite end is a valve F and nozzle F EX- tending beneath the tank is areturn pipe F connected by a vertical joint F with the feed pipe F Onthe opposite end of the pipe F is a valve F and nozzle F Connected tothe nozzle F is a flexible tube G which is attached atthe other end to atube G supported in a water bag G Connected with the nozzle F a flexibletube which is attached at the other end to a tube Gr supported in thewater bag G whereby a complete circulation in the coil and bag issecured. The water bag is secured in a shell G to which straps G are.secured, and whereby the water bag may be fastened to any part of thebody.

To create the desired temperature and circulation of water through thecoil and bag, heat is applied by the flame F S to the part F of thereturn pipe F which is inclosed in a flue F through which the flame Fpasses. Or the heat may be obtained by heating the water in the tank bya flame beneath the tank or by any other convenient means. The othercoil H is adapted to convey air through the spaces E through the screensD and D and through the leaves E or other substance placed between thescreens. The air enters the coilthrough the feed pipe H by natural draftor by mechanical pressure, and passes out of the coil through the end Hthrough the screens and outof the tank from the space above the screensthrough the valve H Connected to this valve is a flexible tube Hattached at the other end of the tube is a double valve H and a funnel Hadapted to cover the nose and mouth over which it is secured by thehead-straps H In the valve H a member H closes the opening of theflexible tube, another member H closes the opening H through which thebreath is free to pass, but no air may enter from the outside.

It is obvious that the temperature of the air may be regulated either bythe heat of the water surrounding the coil in the tank or by the flameof a lamp applied to the inlet at H in the same manner as described andillustrated in connection with the water coil. Various methods ofheating the water in the tank and thereby regulating the temperature ofthe air in the funnel over the face and of the water in the bag may beadapted as the location and convenience therein provide, hence I do notconfine myself to the flame of a lamp but claim the right to use themost available and desirable means for that purpose. It is also obviousthat the medicinal substances placed between the screens may be solidsor fluids suspended in suitable materials through which the air willpass and be thereby saturated. It is obvious also air not medicated maybe heated and inhaled from the tank, and that air instead of water maybe heated and passed through the water pipe coil and bag.

hat I claim as new and desire to secure by Letters Patent is:

1. An inhaling device consisting of a rectangular tank channeled aroundthe top edge and adapted thereby to form a water compartment for theflange of a lid; a lid having a closable valve said lid being adapted tocover said tank and having a flange adapted to fit into said watercompartment; a plate supported horizontally in the central part of saidtank and adapted to close the lower part of the tank; a pair of screensspaced from each other vertically and supported in said tankhorizontally above said plate; an air pipe coil in said tank below saidplate one end of said coil extending through the wall of said tank andthe other through said plate; a flexible tube having a funnel, said tubebeing attached to said valve on said lid as described.

'2. The combination with a rectangular tank the upper part thereofhaving an interior fold adapted to form a water compartment around saidtank, of a lid having a flange part adapted to be inserted in said waterco Apartment in said folded part of said tank, and a closable valve inthe top of said lid; a series of projections supported on the interiorof said tank and spaced from each other vertically; a plate supported onthe lowest of said projections said plate forming a cover for the lowerpart of said tank; a pair of screens supported on said projections andspaced from said plate and from each other vertically; a hot water pipecoil in said tank below said plate; an air pipe coil in said tank belowsaid plate one end of saidpipe extending through said plate; an elastictube secured to said valve.

on said lid, and a funnel secured on the other end of said tube adaptedto cover the nose and mouth of a person.
